ATTORNEY Patented Apr. 24, 1951 UNITED STATES PATENT OFFICE- 4 v i L 2,55o,4o0` i FLOOR DRAIN 'Edward W. N. Boosey, Detroit, Mich. Application April 19, 1946, Serial No. 663,581

This invencin relatestdflor drains the object l plate separatingI the chambers, `a covermember having an apertured portion through which4 fluid may-discharge to the first chamber and including adepending ange spaced from the partition separating the chambers and a basket in the bottom of the inlet'cha-mber into which solid matter carriedl by the inflowing liquid'is deposited whereby fluid flowing through the outlet is practically freed of solid matter owing to the sewer.

These and other features and objects of the invention are hereinafter more fully described and claimed anda device embodying my invention is shown in the accompanying drawing in which-f Fig. 1 is a plan view of the'device.

Fig. 2 is a section taken on line 2--2 of Fig. l. 20

In the preferred form of the invention in the drawings shown, the device comprises a body I having a ange 2 at its upper end providing a shoulder 3 on which a cover member 4 is supported. The said cover member has a short depending plate 5 having an aperture 6 therein and. an additional depending plate I having transverse apertures 9 and I0 therein in vertically spaced relation. The plate I is in vertical alignment with the inner wall Il of the chamber I2 30 and is spaced from its upper end dening the uid passage 8 between chambers I2 and I8 as shown in Fig. 2. 'I'he cover member 4 has a series of apertures I3 and a series of apertures I4 therein through which sewage containing solid 35 matter may 4pass and collect within basket I5.

The basket is provided with a bail having inner ends I6 and I'I extending through apertures provided therefore in the basket I5. By removal of the cover 4 the basket may be removed to dispose 40 of the solid matter accumulating therein. The

bottom wall of the chamber AI8 is provided with an opening I9 which has an inwardly extending circular flange 20 to receive the inlet end of a trap 2| adapted to be connected at the discharge 45 end 22 with a sewer.

` f By means of the said apertured plates 5 and l,

the rising liquid passes through the apertures in the plates to the outlet chamber I8 and the heavier Aparticles of solid matter deposit in the 50 of the water are discharged through the passage 55 8 and aperture 9 and thence to the sewerx If the inflowing'liquid isrgreater in volumethan'the volume discharging through the passage'. and

[aperture 9,1the surface of theliquid and Yfloating material. thereon maypass through the said apertures. 6 and I0 in the plates 5 and 'I to the sewer. The plates 5 and 1 are preferably integral-with the cover member whereby upon removal of the cover the plates are likewise removed thereby permitting access `to the interior of the chamber I8; In the event the `passagewewlbetween the platel and the upwardly extended ange 20 becomes clogged, removal of the cover member permits removal of the accumulated solid matter. 'I'he inlet end 2Ia of the trap 2I is preferably internally threaded to receive a sealing plug (not here shown), which, when positioned therein, prevents backflow from the sewer.

The aperture I0 in the plate I .permits seepage through the aperture I4 to the outlet chamber I 8 in the event of accumulation of material to cover the lower end of the plate 5. Also in such case water flowing through apertures I3 also flows through the apertures 6 and Ill in the plates 5 and 1.

It is believed obvious from the foregoing description that removal of the cover member permits access to the interior of the drain and removal of the basket I5 and the removal of accumulated matter between the flange 1 and the flange 20. The plate 1, here shown as integral with the cover member, may be made integral with the body.

Having thus briefly described my invention, its utility and mode of operation, what I claim and desire to secure by Letter Patent of the United States is:

1. Aiioor drain comprising a body having inlet and outlet chambers, a cover on said body for said chambers, said cover having a depending plate separating said chambers, the lower end of said plate being spaced from the bottom of said outlet chamber defining a uid passage between said chambers, said plate having an aperture adjacent its lower end, a second plate shorter than said rst plate depending from said cover into said inlet chamber in parallel spaced relation to said first plate and having a transverse aperture therein, and a receptacle in the bottom of the inlet chamber the upper end of which is approximately in alignment with the bottom of said outlet chamber, said receptacle providing for the deposit of solid matter therein and permitting free flow of liquid to said outlet chamber.

2. A' floor drain comprising a hollow body having inlet and outlet chambers, a cover member on said body common to both said chambers, said cover member having apertures in that portion thereof covering the inlet chamber, said cover member including a depending plate separating the inlet chamber from the outlet chamber and terminating above the inner wall of the inlet chamber defining a, uid passage, an apertured depending plate upon the under Side of the apertured portion of said cover member, being shorter than said first depending plate, and an outlet conduit connected with said outlet chamber. Y

3. A oor drain comprising a hollow body having inlet and outlet chambers, a cover member on said body common to both said chambers, the cover member having an integral depending vplate terminating above and in vertical alignment with the inner wall f said inlet chamber defining a uid passage between said chambers, there being transverse apertures in said depending plate, an apertured depending plate upon the under side of the apertured portion of said cover member, and a basket in the bottom of said inlet chamber.

4. A floor drain comprising a hollowbody having an inlet chamber on one side and an outlet chamber of less depth than the inlet chamber on the other side, a cover member on said body for said chambers having an integral depending plate terminating above and aligned with the' inner wall of the inlet chamber defining a fluid passage between said chambers, the cover member having apertures in the portion thereof above the inlet chamber, the outlet chamber having a anged opening in the bottom thereof, an outlet conduit extending into the said opening and terminating above the lower edge of said depending plate, the latter having a series of transverse apertures permitting seepage from the inlet chamber to the outlet chamber when the accumulated solid matter in the inlet chamber engages Ythe lower edge of said depending plate closing off said fluid passage, and an apertured depending plate upon the under side of the apertured portion of said cover member, being shorter than said first depending plate.
